QLD Government State Rebates

The government rebate is an initiative by Australia’s government that aims to provide affordable solar energy to all the citizens looking to install a solar system. This initiative is known as the Small-scale Renewable Energy Scheme. The government awards people differently depending on the number of STCs your system gets in the region or zone you live in.

Queensland provides a number of solar rebates to its residents. The rebates vary depending on the size. The larger the system, the higher the rebate.

All Queenslanders are encouraged by the state to apply for interest-free loans for solar as well as solar storage provided by the government. The loans enable people to buy solar systems without spending a lot of money in the initial installation stage.

This arrangement is designed to be a win-win for the people as well as the government. The solar panels installed can pay for themselves after approximately three years from electricity savings and the feed-in tariffs for all grid-connected systems in QLD.

Queensland does not provide rebates to its residents at a state level, but all people planning to install the system get the rebates from the government’s STC scheme. Queenslanders are lucky to get the highest number of STCs in the whole of Australia because it is under zone 1. So, one KW gets an STC of 1.622. Below is an example of how many STCs you will get for your system.

Yes, solar panels store energy through batteries. The batteries store all the energy harnessed by your system to use later. The batteries come with their own inverters that convert the solar energy into electricity. So, when the panels are not producing energy, you can draw power stored by your batteries.

This will depend on how much sunlight you receive in the region you live in and the size of the system you have. Generally, most solar systems do not produce enough power to support all your household needs. That is why most homeowners who have installed solar systems remain in contact with their utility companies.

Solar systems have a lifespan of 25 to 30 years, according to the industry standard. The system loses its efficiency gradually. For the first ten years, it loses 10% of its efficiency. By 20 to 30 years, it loses about 20%, which means you should consider upgrading the system by the time it reaches 40 years.

Typically, most panels come with a linear performance warranty of 20 to 30 years to ensure the system maintains the production capability. The system also comes with a product warranty to protect you from costs that may come up in case of defects or poor installations. The product warranty period depends on your installer.
